Inverted metallurgical microscope MJ42
Inverted metallurgical microscope MJ42

Inverted metallurgical microscope MJ42 employs excellent infinity optical system and modularity design concept to achieve easy system upgrade and realize functions of polarizing observation, dark field observation. The compact, stable and high-rigidity body, fully meets the anti-vibration requirement for the operation. The ergonomic design makes the operation more convenient and comfortable in a wider space. This inverted metallurgical microscope is an ideal instrument for the research of metallurgy, mineralogy, and precision engineering to study the of the microstructure and surface morphology.
